Two weasels are in a bar drinking.

One of them starts to insult the other.

In a loud voice he screams "I slept with your mother."

The bar gets quiet as everyone listens for what the other weasel will say.

Again the first weasel screams " Didn't you hear me? I said I slept with your mother.  And she was crap!"

To which the second weasel replies "Go home dad, you're drunk".
